This handsome man is looking at a beautiful woman.

The flag is a filename in which the woman's face is stored. Use only characters that are at least 90% visible.

Flag format: 1753c{filename}


Provided Image


Step 1: EXIF Metadata

I ran exiftool to inspect any metadata that might help.

Nothing particularly useful stood out in the metadata.


Step 2: Reverse Image Search

Next, I turned to Google Image Search.

Among the results, two sites stood out — Facebook and Vagabundler. I went ahead and explored the Vagabundler page.


Step 3: Clue From the Source

The first image on the site caught my attention. Looking at the browser tab title gave me a very promising filename: Aphrodite_final.j.

Based on the challenge description, I used this filename as the flag.


Step 4: Submitting the Flag

1753c{Aphrodite_final.j}

Correct!


Final Flag

1753c{Aphrodite_final.j}
